Abstract
A method, system, and apparatus for mass spectroscopic analysis of an analyte solution in which a liquid volume of the analyte solution is irradiated with a light source resulting in desorption of solution-specific ions into a surrounding gas to produce gas-phase ions, the gas-phase ions are transferred to an inlet port of a mass analyzer, and the gas-phase ions are mass analyzed. More specifically, the apparatus may include a laser configured to pulse irradiate a surface of the analyte solution, a mass spectrometer configured to mass-analyze the gas-phase ions according to the mass-to-charge ratio, and a transfer mechanism configured to transfer the gas-phase ions to an inlet port of the mass spectrometer.
